  2. Hello. I want to investigate the effects of putting two types of patch antennas on top of each other. I have followed the example guide on how to make a patch antenna using the planar Multilayer infinite substrate. If I were to want to put a second substrate and antenna on top of the example, is there anything I need to watch out for in order to ensure accurate results? Is it as simple as adding another substrate layer using the Planar Multilayer Substrate and drawing another patch on top?
  3. Apply the angular displacement carefully ! The results in optistruct depend on the angular displacement (in the second step) which is not the case in the CEA formulation ...
  4. Hi Can you share a screenshot ? Yann
  5. Thanks @Adriano A. Koga I referred OS-T_1371 and with the help of Altair support I successfully run the model.
  6. i believe you need to create your model manually in RADIOSS user profile to input this kind of motion. I'm not sure HF can create these rotational BCs directly.
  7. Have you take a look at these tutorials from OS documentation? First you impose a clamping force, then apply a small rotation and then run complex modal analysis. If that's what you mean by roatation, it is all there in this tutorial. OS-T_ 1370 Complex Eigenvalue Analysis of a Reduced Brake System.pdf OS-T_ 1371 Brake Squeal Analysis of Brake Assembly.pdf
  8. Hi, I hope the following post about the activation of Embed license helps.
  9. As you does not have valid student "status", I don't know if it's possible for you to request a student release. Maybe another forum admin will respond you on this subject. In the meantime, you can continue to learn other softwares
  10. Hi Vishrut, After downloading the license file, rename it to altair_lic.dat and place the same in the <installation directory>/security folder If you have already done the above and still face the error, Use windows folder options / view > display file name extensions, to make sure the file is named altair_lic.dat and not altair_lic.dat.dat, You need to confirm if the Ethernet address in the license file is the correct one and matches the one in your machine. When you open the license file in a text editor you will see an Ethernet address there in a line that says "ETHERNET = The Ethernet ID is the ID of your machine which is exactly 12 hexadecimal numbers. For example D4WRF478F398 Run ipconfig/all in command window and check for physical address under Ethernet adapter local area connection: The listed physical address under Ethernet adapter local area connection should be used to generate the license file, if there is no listing of Ethernet adapter local area connection, the address under Wireless Adapter LAN Wifi must be used. That means if the address provided as above does not match the one in the license file, please request for the license file again with the correct Ethernet ID here https://studentedition.altair.com/
  11. Hi, I graduated in Mechanical Engineer last November and I don't have a job yet - COVID-19 hit Italy very hard. Still, I wish to learn HyperMesh - actually I'm studying several FEA software as I wish to become a Stress Engineer. Am I eligible to acquire the Student Edition? If so, how? I'm a student, but with no University or company.
  12. Hello, I need to know if it is possible to simulate tools that rotation in opposite directions to form a blank (see attached image for a visual explanation). Note: In green is the blank which is the profile of a cylinder. Thank you in advance KBE
  13. Hello, I have a blank of which the thickness varies in different sections of it (see attached image). Green represents the shell, black the thickness variation and dotted line is the rotation axis as this image shows the profile of a cylinder. I need to know if we can define the different thickness values according to the section on hyperform as a shell. Thank you in advance KBE
  14. Hello, As i am trying to do optimization in my case my model is alaredy defined with number plies, i would like to do direct size optimization instead of free size optimization. Is it possible? Becuase i have tried with the composite size option and gave all the required value at the end in output i have chosen SZTOSH and submitted for run, after the analysis i got this message " NO DESIGN MATERIAL OR DESIGN VARIABLES FOUND : ANALYSIS ONLY" and it gives normal analysis output. Could you please halp me out with this. For your refernce i have attach .output file. HyBo_DG-Rahmen_v34_NL_200803_V1.3_CFply_SO.out
  15. Hello flyforever, Try the following: Open in the menu Preferences->Options Go to Lighting Here you can change direction, specular color, flat/smooth or use multiple lights I hope I could help you. Best Regards, Mario

    FEM meshing

    This is the Altair Feko forum therefore a FEM mesh refers to a tetrahedral mesh where the EM fields are solved. That does not sound right. If you cannot attach the model, please ask your study leader for Feko support contact details in your country.
  17. @Ankitmehta11 Did you got the results considering the rotation of the disc?? I am also working on similar kind of analysis. looking for some inputs/guidance
  18. Hello. Does anybody knows how to do a crossplot in hypergraph by using scripting? I already have my 2 curves, but I need to do the crossplot operation in code. Thank you
  19. I have received many error messages so far and all the errors have been resolved by doing some research in the forum, but now I am getting the error message: "INTERNAL PROGRAMMING ERROR # 8011" and I cannot find any information for this. Can you tell me how I can fix this error? I have two different versions of hyperworks and I tried both of them: 2019.1 and 2020 Thanks in advance. Best regards, Oguzhan
  20. Yesterday
  21. I have a C++ dll written using Visual Studio 2015 which is called by a userFunction block. The dll includes a custom block which asks for a single integer input. I am able to use the API to create the dialog, set a default for the parameter, etc, but for the life of me, I can't figure out how to put the response back into my dll. Can someone please help?
  22. do you have altair_lic.dat file ? if yes, are you sure that the *dat file is in the right directory ?
  23. Jackie


    Thanks for your help Yann!
  24. Do you speak about CFD Meshing or Mechanical meshing? Do you make your mesh in batch mode or interactive mode?
  25. Creating a bolt connector. i make a work around and create a mid node on the line and use a node to create it
